O-rings are medium to high load seals for axial compression with a low spring back.
These can be used when a medium to high leak tightness is required but almost no flexibility is needed.
O-rings are available for internal and external pressure and are also available as shaped seals.

Features / requirements
Easy & approved design
Feasibility of complex shapes
Functionality not influenced by the
medium (plastic, abrasives, pollution,… )
Lower spring back
Medium to high load
Adaptable to specific application demands
– Gas flied
– Spring energized
– Higher pressure
– High temperature (+600°C)
– Extremely high pressure
Wide sealing surface, low seating stress
Chamfer joints (three point sealing)
Very high temperature resistant (gas filled)
Unlimited shelf life
OG- & OS-seals
Some O-rings can be gas filled or used in combination with a spring for very rare applications, please contact HTMS for the feasibility if you consider one of these specific O-rings.
